# Change your outgoing Email IP address on a WHM / cPanel server

Use the below listed guide to change the outgoing mail IP address for the **entire server**:

1. Log into WHM and go to the '**Exim Configuration Manager**':

1. Through the **‘Basic Editor’**, select the '**Domains and IPs**' section:

Followed by turning the following setting to **‘On’** and save your changes.![Instructions for configuring custom IP for outgoing SMTP connections in mail settings.](https://cdn.document360.io/d809f158-d4f4-47ff-83d4-18d9c9f7a04d/Images/Documentation/Screenshot 2026-06-06 at 8.53.06 am.jpg)

1. SSH to the server and edit the **/etc/mailips** file in your favourite command line text editor. If you're unsure of which text editor to use, '**nano'** is the easiest for beginners.

`root@server ~]# nano /etc/mailips`

S

1. Edit the file to make sure it looks like this:

`*: 123.123.123.123`

*(Make sure you replace 123.123.123.123 with the actual IP address you wish to send email from).*
2. Save the file.

That's it! Your Exim mail server will now send email from the IP address you've specified in the /etc/mailips file.

> [!WARNING]
> Please Note!
> 
> You will need to make sure your domain's SPF record specifies the new IP address or your email may not be accepted by the receiving host. i.e. "v=spf1 a mx ip4:123.123.123.123 ~all"
